The MAX9511 operates with a 4.5V to 5.5V power sup-
ply for video (RGBHV), while DDC and SYNC operate
from 2.3V to 3.6V and 4.5V to 5.5V supplies.

The MAX9511’s high-frequency performance requires
proper layout and bypassing. For best performance,
place components as close to the device as possible.
Digital or AC transient signals on AGND can create
noise at the outputs. Return AGND to the lowest imped-
ance ground available. Bypass the analog supply
